Microdomain regions

When r was less than 0.46 (Fig. 9a), the P4VP layer surrounded some microspheres in groups (r = 0.33). The K r = 0.33 was 2.48. This indicates that the amount of B1 block copolymer was insufficient to surround each microsphere separately. When r was larger than 0.46 (Fig. 9c), the wide dark regions of P4VP were also observed. These regions were horizontally oriented lamellar microdomains of Bl, resulting in a minimization... 

The most extensively studied TRIAD is Parkin, shown schematically in Figure 4.5A. The N-terminus contains a region homologous to ubiquitin called the ubiq-uitin domain (UbD), which interacts directly with proteasomes. The C-terminus contains two RING fingers (Rl, R2) separated by a cysteine-rich in-between i ING (IBR) region. This TRIAD motif mediates E3 activity and interacts with molecular chaperones. The last three amino acids of Parkin interact with a PDZ domain and possibly function to anchor Parkin to lipid microdomains. 

If the PEP-PEE triblock chains are arranged in microdomains separated by well-defined interfaces, then the additional fast relaxation process observed by NSE would result from the undulation motions of the interface. The thermal motions of the interface are driven by the surface tension and overdamped. With an effective viscosity r eff in the interfacial region, the relaxation rate if Q) ... 

On an even smaller scale is the microdomain structure at 0.01-. im spacing. This is interpreted as a structure where the crystallites of about 0.01-pm spacing arc tied together by molecules in the amorphous regions. Plasticizer swells llie amorphous regions without dissolving Hie crystallites. 

Fig. 4 (a) SFM phase image (3x1.5 im) of the surface structures in SB47 films annealed in vacuum at 120°C. The white contour lines are taken from the height image (not shown) and mark the borders between the flat regions, as well as the transition region between the indicated terraces, (b) Spacings of cylindrical microdomains as a function of the local film thickness... 

Fig. 3 Example of the microdomains created by embedding luminescent indicator-loaded silica gel nanoparticles into poly(dimethylsiloxane) before cross-linking to fabricate films for oxygen optosensing. The largest circles represent the silica particles the black lines represent the PDMS polymer chains, while the smallest circles represent the indicator dye molecules (the black circles depict those located in the organic polymer-free silica regions and the gray circles stand for those adsorbed on silica regions in contact with the PDMS)...
